"According to the versions of the kernel packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - The hid_input_field() function in
    'drivers/hid/hid-core.c' in the Linux kernel before 4.6
    allows physically proximate attackers to obtain
    sensitive information from kernel memory or cause a
    denial of service (out-of-bounds read) by connecting a
    device.(CVE-2016-7915i1/4%0

  - The Linux kernel, before version 4.14.2, is vulnerable
    to a deadlock caused by
    fs/ocfs2/file.c:ocfs2_setattr(), as the function does
    not wait for DIO requests before locking the inode.
    This can be exploited by local users to cause a
    subsequent denial of service.(CVE-2017-18204i1/4%0

  - The vmw_gb_surface_define_ioctl function (accessible
    via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in
    drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux
    kernel through 4.11.4 defines a backup_handle variable
    but does not give it an initial value. If one attempts
    to create a GB surface, with a previously allocated DMA
    buffer to be used as a backup buffer, the backup_handle
    variable does not get written to and is then later
    returned to user space, allowing local users to obtain
    sensitive information from uninitialized kernel memory
    via a crafted ioctl call.(CVE-2017-9605i1/4%0

  - Use-after-free vulnerability in the nfqnl_zcopy
    function in net/netfilter/nfnetlink_queue_core.c in the
    Linux kernel through 3.13.6 allows attackers to obtain
    sensitive information from kernel memory by leveraging
    the absence of a certain orphaning operation. NOTE: the
    affected code was moved to the skb_zerocopy function in
    net/core/skbuff.c before the vulnerability was
    announced.(CVE-2014-2568i1/4%0

  - It was found that the Linux kernel's ISO file system
    implementation did not correctly limit the traversal of
    Rock Ridge extension Continuation Entries (CE). An
    attacker with physical access to the system could use
    this flaw to trigger an infinite loop in the kernel,
    resulting in a denial of service.(CVE-2014-9420i1/4%0

  - An integer overflow vulnerability was found in the
    ring_buffer_resize() calculations in which a privileged
    user can adjust the size of the ringbuffer message
    size. These calculations can create an issue where the
    kernel memory allocator will not allocate the correct
    count of pages yet expect them to be usable. This can
    lead to the ftrace() output to appear to corrupt kernel
    memory and possibly be used for privileged escalation
    or more likely kernel panic.(CVE-2016-9754i1/4%0

  - A symlink size validation was missing in Linux kernels
    built with UDF file system (CONFIG_UDF_FS) support,
    allowing the corruption of kernel memory. An attacker
    able to mount a corrupted/malicious UDF file system
    image could cause the kernel to crash.(CVE-2014-9730i1/4%0

  - In was found that in the Linux kernel, in
    vmw_surface_define_ioctl() function in
    'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file, a
    'num_sizes' parameter is assigned a user-controlled
    value which is not checked if it is zero. This is used
    in a call to kmalloc() and later leads to dereferencing
    ZERO_SIZE_PTR, which in turn leads to a GPF and
    possibly to a kernel panic.(CVE-2017-7261i1/4%0

  - A race condition flaw was found in the way the Linux
    kernel keys management subsystem performed key garbage
    collection. A local attacker could attempt accessing a
    key while it was being garbage collected, which would
    cause the system to crash.(CVE-2014-9529i1/4%0

  - A flaw was found in the Linux kernel's implementation
    of i8042 serial ports. An attacker could cause a kernel
    panic if they are able to add and remove devices as the
    module is loaded.(CVE-2017-18079i1/4%0

  - drivers/hid/hid-pl.c in the Human Interface Device
    (HID) subsystem in the Linux kernel through 3.11, when
    CONFIG_HID_PANTHERLORD is enabled, allows physically
    proximate attackers to cause a denial of service
    (heap-based out-of-bounds write) via a crafted
    device.(CVE-2013-2892i1/4%0

  - The __clear_user function in
    arch/arm64/lib/clear_user.S in the Linux kernel before
    3.17.4 on the ARM64 platform allows local users to
    cause a denial of service (system crash) by reading one
    byte beyond a /dev/zero page boundary.(CVE-2014-7843i1/4%0

  - A divide-by-zero vulnerability was found in a way the
    kernel processes TCP connections. The error can occur
    if a connection starts another cwnd reduction phase by
    setting tp-i1/4zprior_cwnd to the current cwnd (0) in
    tcp_init_cwnd_reduction(). A remote, unauthenticated
    attacker could use this flaw to crash the kernel
    (denial of service).(CVE-2016-2070i1/4%0

  - The adjust_branches function in kernel/bpf/verifier.c
    in the Linux kernel before 4.5 does not consider the
    delta in the backward-jump case, which allows local
    users to obtain sensitive information from kernel
    memory by creating a packet filter and then loading
    crafted BPF instructions.(CVE-2016-2383i1/4%0

  - System using the infiniband support module ib_srpt were
    vulnerable to a denial of service by system crash by a
    local attacker who is able to abort writes to a device
    using this initiator.(CVE-2016-6327i1/4%0

  - A security flaw was found in the Linux kernel in the
    mark_source_chains() function in
    'net/ipv4/netfilter/ip_tables.c'. It is possible for a
    user-supplied 'ipt_entry' structure to have a large
    'next_offset' field. This field is not bounds checked
    prior to writing to a counter value at the supplied
    offset.(CVE-2016-3134i1/4%0

  - An out-of-bounds access issue was discovered in
    yurex_read() in drivers/usb/misc/yurex.c in the Linux
    kernel. A local attacker could use user access
    read/writes with incorrect bounds checking in the yurex
    USB driver to crash the kernel or potentially escalate
    privileges.(CVE-2018-16276i1/4%0

  - drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux
    kernel before 4.5.3 allows local users to cause a
    denial of service (kernel memory write operation) or
    possibly have unspecified other impact via a crafted
    number of planes in a VIDIOC_DQBUF ioctl
    call.(CVE-2016-4568i1/4%0

  - The usb_serial_console_disconnect function in
    drivers/usb/serial/console.c in the Linux kernel,
    before 4.13.8, allows local users to cause a denial of
    service (use-after-free and system crash) or possibly
    have unspecified other impact via a crafted USB device,
    related to disconnection and failed
    setup.(CVE-2017-16525i1/4%0

  - The Linux kernel is vulnerable to a NULL pointer
    dereference in the ext4/xattr.c:ext4_xattr_inode_hash()
    function. An attacker could trick a legitimate user or
    a privileged attacker could exploit this to cause a
    NULL pointer dereference with a crafted ext4 image.

Venkatesh Pottem discovered a use-after-free vulnerability in the
Linux kernel's CXGB3 driver. A local attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2015-8812)

Xiaofei Rex Guo discovered a timing side channel vulnerability in the
Linux Extended Verification Module (EVM). An attacker could use this
to affect system integrity. (CVE-2016-2085)

It was discovered that the extended Berkeley Packet Filter (eBPF)
implementation in the Linux kernel did not correctly compute branch
offsets for backward jumps after ctx expansion. A local attacker could
use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2016-2383)

David Herrmann discovered that the Linux kernel incorrectly accounted
file descriptors to the original opener for in-flight file descriptors
sent over a unix domain socket. A local attacker could use this to
cause a denial of service (resource exhaustion). (CVE-2016-2550)

It was discovered that the Linux kernel did not enforce limits on the
amount of data allocated to buffer pipes. A local attacker could use
this to cause a denial of service (resource exhaustion).
(CVE-2016-2847).

In some cases, the kernel did not correctly fix backward jumps in a
new eBPF program, which could allow arbitrary reads. (CVE-2016-2383)

The kernel incorrectly accounted for the number of in-flight fds over
a unix domain socket to the original opener of the file descriptor.
Another process could arbitrarily deplete the original file opener's
maximum open files resource limit. (CVE-2016-2550)

A resource-exhaustion vulnerability was found in the kernel, where an
unprivileged process could allocate and accumulate far more file
descriptors than the process' limit. A local, unauthenticated user
could exploit this flaw by sending file descriptors over a Unix socket
and then closing them to keep the process' fd count low, thereby
creating kernel-memory or file-descriptors exhaustion (denial of
service). (CVE-2016-2847)"

security and bugfixes.

The following security bugs were fixed :

  - CVE-2015-1339: A memory leak in cuse could be used to
    exhaust kernel memory. (bsc#969356).

  - CVE-2015-7799: The slhc_init function in
    drivers/net/slip/slhc.c in the Linux kernel did not
    ensure that certain slot numbers are valid, which
    allowed local users to cause a denial of service (NULL
    pointer dereference and system crash) via a crafted
    PPPIOCSMAXCID ioctl call (bnc#949936 951638).

  - CVE-2015-7872: The key_gc_unused_keys function in
    security/keys/gc.c in the Linux kernel allowed local
    users to cause a denial of service (OOPS) via crafted
    keyctl commands (bnc#951440).

  - CVE-2015-7884: The vivid_fb_ioctl function in
    drivers/media/platform/vivid/vivid-osd.c in the Linux
    kernel did not initialize a certain structure member,
    which allowed local users to obtain sensitive
    information from kernel memory via a crafted application
    (bnc#951626).

  - CVE-2015-8104: The KVM subsystem in the Linux kernel
    allowed guest OS users to cause a denial of service
    (host OS panic or hang) by triggering many #DB (aka
    Debug) exceptions, related to svm.c (bnc#954404).

  - CVE-2015-8709: kernel/ptrace.c in the Linux kernel
    mishandled uid and gid mappings, which allowed local
    users to gain privileges by establishing a user
    namespace, waiting for a root process to enter that
    namespace with an unsafe uid or gid, and then using the
    ptrace system call. NOTE: the vendor states 'there is no
    kernel bug here (bnc#959709).

  - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux
    kernel did not properly manage the relationship between
    a lock and a socket, which allowed local users to cause
    a denial of service (deadlock) via a crafted sctp_accept
    call. (bsc#961509)

  - CVE-2015-8785: The fuse_fill_write_pages function in
    fs/fuse/file.c in the Linux kernel allowed local users
    to cause a denial of service (infinite loop) via a
    writev system call that triggers a zero length for the
    first segment of an iov (bnc#963765).

  - CVE-2015-8787: The nf_nat_redirect_ipv4 function in
    net/netfilter/nf_nat_redirect.c in the Linux kernel
    allowed remote attackers to cause a denial of service
    (NULL pointer dereference and system crash) or possibly
    have unspecified other impact by sending certain IPv4
    packets to an incompletely configured interface, a
    related issue to CVE-2003-1604 (bnc#963931).

  - CVE-2015-8812: A flaw was found in the CXGB3 kernel
    driver when the network was considered congested. The
    kernel would incorrectly misinterpret the congestion as
    an error condition and incorrectly free/clean up the
    skb. When the device would then send the skb's queued,
    these structures would be referenced and may panic the
    system or allow an attacker to escalate privileges in a
    use-after-free scenario. (bsc#966437).

  - CVE-2016-0723: Race condition in the tty_ioctl function
    in drivers/tty/tty_io.c in the Linux kernel allowed
    local users to obtain sensitive information from kernel
    memory or cause a denial of service (use-after-free and
    system crash) by making a TIOCGETD ioctl call during
    processing of a TIOCSETD ioctl call (bnc#961500).

  - CVE-2016-2069: When Linux invalidated a paging structure
    that is not in use locally, it could, in principle, race
    against another CPU that is switching to a process that
    uses the paging structure in question. (bsc#963767)

  - CVE-2016-2184: A malicious USB device could cause a
    kernel crash in the alsa usb-audio driver. (bsc#971125)

  - CVE-2016-2383: Incorrect branch fixups for eBPF allow
    arbitrary read of kernel memory. (bsc#966684)

  - CVE-2016-2384: A malicious USB device could cause a
    kernel crash in the alsa usb-audio driver. (bsc#966693)

The following non-security bugs were fixed :

  - alsa: hda - Apply clock gate workaround to Skylake, too
    (bsc#966137).

  - alsa: hda - disable dynamic clock gating on Broxton
    before reset (bsc#966137).

  - alsa: hda - Fix playback noise with 24/32 bit sample
    size on BXT (bsc#966137).

  - alsa: seq: Fix double port list deletion (bsc#968018).

  - alsa: seq: Fix leak of pool buffer at concurrent writes
    (bsc#968018).

  - alsa: timer: Fix race between stop and interrupt
    (bsc#968018).

  - alsa: timer: Fix wrong instance passed to slave
    callbacks (bsc#968018).

  - arm64: Add workaround for Cavium erratum 27456.

  - arm64: Backport arm64 patches from SLE12-SP1-ARM

  - btrfs: teach backref walking about backrefs with
    underflowed (bsc#966259).

  - cgroup kabi fix for 4.1.19.

  - config: Disable CONFIG_DDR. CONFIG_DDR is selected
    automatically by drivers which need it.

  - config: Disable MFD_TPS65218 The TPS65218 is a power
    management IC for 32-bit ARM systems.

  - config: Modularize NF_REJECT_IPV4/V6 There is no reason
    why these helper modules should be built-in when the
    rest of netfilter is built as modules.

  - config: Update x86 config files: Enable Intel RAPL This
    driver is useful when power caping is needed. It was
    enabled in the SLE kernel 2 years ago.

  - Delete patches.fixes/bridge-module-get-put.patch. As
    discussed in
    http://lists.opensuse.org/opensuse-kernel/2015-11/msg000
    46.html

  - drm/i915: Fix double unref in intelfb_alloc failure path
    (boo#962866, boo#966179).

  - drm/i915: Fix failure paths around initial fbdev
    allocation (boo#962866, boo#966179).

  - drm/i915: Pin the ifbdev for the info->system_base GGTT
    mmapping (boo#962866, boo#966179).

  - e1000e: Avoid divide by zero error (bsc#965125).

  - e1000e: fix division by zero on jumbo MTUs (bsc#965125).

    algorithm (bsc#965125).

  - ibmvnic: Fix ibmvnic_capability struct.

  - intel: Disable Skylake support in intel_idle driver
    again (boo#969582) This turned out to bring a regression
    on some machines, unfortunately. It should be addressed
    in the upstream at first.

  - intel_idle: allow idle states to be freeze-mode specific
    (boo#969582).

  - intel_idle: Skylake Client Support (boo#969582).

  - intel_idle: Skylake Client Support - updated
    (boo#969582).

  - libceph: fix scatterlist last_piece calculation
    (bsc#963746).
